RinS1
This pin is for input a right audio
signal from an external source (S1
channel). The signal fed into this pin
is presented to Rout1 and Rout2.
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70 k
.

CinS1
This pin is for input a chroma signal
from an external source (S1
channel). It also functions as an
S-mode select switch for the S1
channel. The S mode is selected
when the pin voltage is 2.25 V or
less. The signal fed into this pin is
presented to Cout directly and to
Vout1 and Vout2 after being
combined with the YinS1 signal.
The input dynamic range of this pin
is 2.0 Vp-p and the input resistance is
30 k
.

LinS2
This pin is for input a left audio
signal from an external source (S2
channel). The signal fed into this pin
is presented to Lout1 and Lout2.
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70 k
.

Y/VinS2
This pin is for input a luminance
signal or composite aoudio signal
from an external source (S2
channel). The signal fed into this pin
is presented to Vout1, Vout2, Yout,
and Cout.
The input dynamic range of this pin
is 2.0 Vp-p and the input resistance is
30 k
.
